What is the function of UV ultraviolet glue?

PET plastic boxes are widely used in packaging for food, pharmaceuticals, cosmetics, gifts, electronics, and more. Their popularity stems from excellent barrier properties, high transparency, high and low temperature resistance, and resistance to oil, acids, and alkalis, making them a staple in the packaging industry.

PET plastic box adhesive is a bonding agent specifically designed for PET plastic boxes. Its primary function is to adhere PET plastic boxes to other materials, creating a single unit. PET plastic box adhesive typically comprises PA, specialized PET adhesive, tougheners, thickeners, and mold inhibitors. PA is the most commonly used adhesive type in PET plastic box adhesive; its high strength, toughness, and temperature resistance satisfy the bonding strength requirements of PET plastic boxes.

Using PET plastic box adhesive is straightforward. First, thoroughly clean the surfaces of the PET plastic box and other materials to be bonded, removing moisture, oil, and other contaminants. Next, mix the PET plastic box adhesive according to the proportions indicated, and apply it to the surfaces to be bonded. Finally, press the two surfaces together and allow sufficient time for drying and bonding.

The following points should be noted when using PET plastic box adhesive:

The surfaces of the PET plastic box and other materials to be bonded must be clean, dry, and free of contaminants.

The PET plastic box adhesive must be mixed according to the instructions; otherwise, the bonding effect may be compromised.

The bonding temperature of the PET plastic box and other materials should be moderate; excessively high or low temperatures can affect the bonding effect.

UV curing adhesive is widely used in bonding plastics, paper packaging, and wood. Its mechanism involves a chemical crosslinking reaction; under high-energy UV irradiation, a chemical bond forms between the two materials, resulting in a strong bond.

UV curing adhesive offers advantages of high efficiency, convenience, and speed. It enables large-area bonding without generating heat or toxic gases, minimizing environmental and health impact. Additionally, UV curing adhesive boasts fast curing, high bonding strength, good water resistance, and high temperature resistance, leading to wide use in industrial production and daily life.

The main components of UV curing adhesive are acrylates, peroxides, and initiators; these determine the chemical properties and characteristics. Acrylates are the most common crosslinking agents; they react with oxygen to form a crosslinked network, achieving the adhesive effect.

In addition to crosslinking agents, UV curing adhesive also contains other components such as tougheners, diluents, and preservatives. Tougheners increase the toughness of the adhesive and its low-temperature performance; diluents adjust the viscosity for easier application; and preservatives prevent degradation due to contamination during use.

Using UV curing adhesive is simple: apply it to the surfaces to be bonded, and then irradiate with a UV light source for a specified time. Note that different materials require different irradiation times and power to ensure optimal bonding.

UV curing adhesive is a widely used and highly effective bonding material that achieves strong bonding through chemical crosslinking reactions. When using PET plastic box adhesive, avoid direct skin contact. If accidental contact occurs, rinse thoroughly with water. PET plastic box adhesive is an essential accessory for PET plastic boxes, offering wide application and excellent bonding performance. Using the correct PET plastic box adhesive improves product quality, stability, and lifespan.
